Problems solved by technology

The arrangement of the panoramic camera outside the beam deflection unit has various disadvantages: on the one hand, two cameras and two beam paths must be provided for the field of view of the cameras, and on the other hand, positioning the panoramic camera outside the beam deflection unit would Causes severe unbalances and bending moments on the beam deflection unit, for which corresponding countermeasures have to be taken, which incurs additional costs and makes the system susceptible to disturbances when working in the field...

Embodiment Construction

[0086] figure 1 Shown is a first embodiment of a measuring device 1 according to the invention, figure 2 Shown is a detailed view of a beam deflecting unit 10 according to the design of the invention. Generally speaking, the measuring device 1 is equipped with a measuring head 2 , the housing 5 of which is mounted on a base 3 in a manner to be rotatable about a base axis 4 . The base 3 can be fixed on a stand or a tripod by means of an adapter 51 . The base 3 has a base axis 4 about which the housing 5 can be rotated (manually and / or electrically and controlled by a control unit 9 ). A radiation source 6 for generating measuring radiation 13, a detector 8 for detecting reflected radiation 17 received and preferably reflected by a target object, and for propagating the radiation and collimating measuring radiation 13 and reflected radiation 17 The optical assembly 7 is housed in the housing. Both the radiation source 6 and the detector 8 are components of an Electronic Dis...

Abstract

Some embodiments of the invention relate to a surveying apparatus in the form of a scanner comprising a beam deflection unit, such a beam deflection unit and a measuring method to be carried out with said surveying apparatus. The surveying apparatus comprises a radiation source for generating measurement radiation and a detector for receiving reflected measurement radiation, called reflection radiation for short, which was reflected at an object of interest, wherein measurement radiation and reflection radiation have substantially the same optical path. Situated in said optical path there is a beam deflection unit mounted rotatably about a rotation axis and serving for adjustably aligning the measurement radiation and for capturing the reflected radiation

Description

technical field [0001] The invention relates to a measuring device, in particular realized in the form of a scanning device, in order to generate to scale a three-dimensional image of a measuring object of interest. Background technique [0002] Measuring devices or scanning devices of the type mentioned at the outset are designed for the three-dimensional measurement of spatial regions and / or objects. Typical application examples are the surveying of interior spaces such as churches and workshops, the surveying of large objects such as buildings or aircraft, or forensic surveys of accident scenes. [0003] When measuring these objects, the laser beam of the laser scanning device can be used to scan a predetermined space volume and detect the laser light reflected by the object, wherein the emitted laser beam and the direction of the detected laser light are collected at each moment angle information. The distance between a certain surface point in the volume of space and ...
